Enable or Disable Hibernation OSX

OSX supports real hibernation not only that sleep mode that costs electricity. It really supports it. But you gotta enable or disable it manually. So what to do:

  • open terminal window (I assume you’re logged in with your normal user account)
  • to disable hibernation, and enable standard sleep
    enter this: sudo pmset -a hibernatemode 0
  • to enable hibernation when closing the lid
    enter this: sudo pmset -a hibernatemode 1
  • to Delete the Hibernate Images (based on your RAM Size)
  • enter this: 
  • sudo -s
  • rm /private/var/vm/sleepimage
